By use of a survey that assessed practice patterns and responses to case vignettes of anxiety and depression in the medically ill, 38 psychiatrists were compared with 10 national leaders in consultation-liaison psychiatry.

On the case vignettes, percentage agreement with the experts varied significantly by case and by question.

Fifty-eight percent of the time the psychiatrists agreed with the experts on whether to order laboratory tests as compared with an 81% agreement level on whether to use psychotherapy.

Multiple regression analysis revealed that the best model to predict lower agreement with the experts was years in practice plus percentage of time spent in solo (vs. group) practice (r2=0.40).
